' l Application filed September 4,1903 Serial No. 1"7l, 9l8. (No model.)

T0 all whom, if may concern/.f l l Be it known that'LFRANK S. ALIANo, a'citi# zentof theUnited States, residing inthe borou gh of lBrooklymcity of New York,county of Kings, 'and State of N ew-'YorlLhave .invented certain new and useful Improvements in Locks,of which the following-is aspecication,

reference beingV had therein to the accompanying drawings, which forma partthereof.` My inventionrelates to improvements in locks, ...and moreparticularly`v to a class of Springlocks wherein the bolt or bolts are adapted to automatically enter its or their sockets when the lock is closed. 'i f The-objectof myinvention is to provide a lock of this lcharacter which will becomposed of elements readilyjmanufactured 'atfsmall costand 'so assembledas to produce; a simple mechanism in compact'form. f A further object isto provide a-lock wherein the bolt'or bolts'may to lock the device act solely under their own'spri'ngtension or may be shot 'positively through the medium of alA f A still lfurtherobject is to provide a lock which is especially adapted to beattached to andl form a part lof the, h'asp ofa` trunk or similary lock; anda still further object is tor pr'ovide a lock of this character wherein the'sevsta-bility'to the assembled 'structure- The invention consists in the novel features ofl construction hereinafter `set forth anddescribed, and more particularly the claims hereto appended.-

Referring tothedra'wings, Figure 1 is a pointed out in side elevation of atrunk-lock embodying they preferred form ofmy invention, thelock l proper being in section on-the line 1l 1-of Fig.2.

Fig. 2is a plan view thereof on the line 2 2 of Fig. 1 with the hasp brokenaway todisclose the actuating mechanism contained in the tumbler-chamber of the lock-casing.

point/adjacent to the top of the tumbler-chambera. A M eral parts will be so 'related as to'give greatA f Likev letters refer to like In the drawings, A and B indicate the parts whichrespectivelycarry the lock-hasp C and the vsocket-plate D. The construction andv arfr 'l rangementof these parts, except the .detailed 'construction of the socket-plate D, areWellknown in this art and form no part of this inf` j vention. The hasp C carries the look-casing, which is constituted of tfwoisuperposed cylinj-Y drical portions a and 7) forni-1ng an upper or tumbler ychamber a and a lower or bolt chamber b". 'The tumbler-chamber a is .of greater diameter than the bolt-chamber 7)', which arrangement `results in the formation of the oft' j set portion fc presenting upwardly within. the chamber a a seat and bearing for the tumblers and a support 'for the tumbler pivot-pinf-and for the tumbler-springs-tensioning pin and; downwardlya contact-face adapted to engage the 'socket-plate D. 'The said casing is closed by the bottom lplate d, and preferably all parts thereof areV made: integral, being either stamped orl turned lfrom a single piece" ofy metal.

` The bottom yplate d' has `firmly'- attached.A

thereto thekey-stud @,'wh-ich extends to a Substantiallyopposi'tely .disposed boltholes are providedfin .the p ortion'b, and seated in the bolt-chambertl and projecting through these openingsarewbolts f and'g. "The'bolts n are disposed upon opposite sides;` of the stud g e, rest uponthe bottom plated, and move in a way formed by said stud and `the springi seatslt and z'. Said bolts and theirl spring-seats being idenj tical, a detailed description of but one of them will be entered into, the corresponding'part inthe other bolt being designated bythe sec? ond referenceeletter in each'instance.

The detailed construction of i Each bolt consists of thel lo'ekingportion having the usual plane face adapted to engage the lock-socket and the beveled surface adapted toengage said socket to retract the bolt to insure an automatic engagement of the bolt therewith. This portion of said bolt differs from the ordinary bolts solely in that the bolt. Within the bolt-chamber the side of the bolt toward the stud e is reduced to provide a narrow shank f2 g2 with the twofold object to permit the bolt to slide freely past said stud and to provide suitable space for the means actuating said bolts. The shank f2 g2 on its outer side is provided with an abutment f3 g3, the opposite sides of which, respectively, are curved so as to serve by engagement with the portion b to limit the extent vof projection of the bolt therefrom and fiat tov act as a seat for the spring j j. A shoulder f4 g4 on said shank is so disposed thereon as to engage the spring-seat it z' to limit the extent of retraction of the bolt by the key. The said bolt-shank f2 g2 has on itsvlower face adjacent to said stud e a channel cutaway, as l shown in Fig. l at f5 Q'the object of lwhich cut will appear hereinafter. The upper face of said shank is provided with a way disposed between said stud c and the portion b, as at f g, and the outer corner of said way is scarfed away slightly to facilitate the engagement and disengagement of the actuating mechanism with said bolt. y

The spring-seats c' each preferably consist of an L-shaped piece of metal soldered to the portion ZJ, and the springs 7' j are respectively disposed between the short arm of said seats and the seats formed by the abutments f3 g3, the long arm of said seats serving to confine the springs j j to the chamber formed thereby, together with the bottom d and the closure of the chamber A link c is pivotally mounted on the stud e and projects laterally thereof into engagement with the cuts f5 g5, the function of said linkbeing to insure synchronous movement of said .bolts under all conditions of service and wear. l The sides of this link are preferably curved to prevent any tendency to bind in said channel and to avoid the sacrifice of strength of material in the bolts.

The' actuating mechanism comprises a rotary key-disk m, pivotally mounted on the stud e, which is fitted to and closes the mouth ofthe chamber 7)being flush with the annular offset-portion c and therewith constituting the bottom of the. chamber a'. This disk m rests directly upon the bolts f and g and confines these bolts within the chamber b, holding them firmly in place in a manner to insure against their displacement through any strains and pressures` placed thereupon. To increase the efiicieney of the said diskfor this purpose, I extend the tumbler-catch m carried thereby to a height which will insure its engaging the hasp or other plate closing the chamber a', and also provide a second bearing-piece m2 of similar height, so disposed on said disk as not to interfere with the free rotation thereof by contact with other parts of the actuating mechanism.

The disk m is provided with two downwardly-projected rounded studs mf m, arranged eccentrically of said disk, which normally are seated in the space in the chamber ,bl between the shanks f2 rf opposite to the Waysf g, which they are adapted to enter when the disk is rotated.

A tumbler fulcrum-pin n is permanently attached to or mounted on the abutment c, said pin being of sufficient height to engage the hasp or other closurel plate to give rigidity thereto. Mounted upon this pin are a plurality of tumblersa of well-known construction, adapted to cooperate with the tumblercatch m to prevent the rotation of the disk m. .These tumblers are of' suflicient thickness to extend to the top of the chamber m, thus avoiding their disarrangement. A secon d pin 0 is also mounted on the said shoulder or abutment c in such juxtaposition to the pin o1. as to l serve as a retaining and tensioning means for the tumbler-springs o. The lowermost tumbler a' and spring 0 rest upon the abutment or shoulder c.

The disk m is provided with the usual keyrecess m* in the usual relation to the tumblers.

A further detailed description of the tumblers and their mode of operation will not be entered into, such being old and well known in this art.

In the modification shown in Figs. 5 and 6 the construction is identical with that of the preferred form, except that a single bolt q is employed. This bolt is provided with thc curved outer edge q and with a central slot forming the double shank q2 q2, each having an abutment g3 Q3, which limits the extent of projection of the bolt and acts as a double spring-seat. The spring-seats lr, however, are formed of a single metal blank, the rear of which forms a way for the bolt and also serves to limit the amount of retraction of the bolt. The bolt is provided withbut a single way s, which is adapted to cooperate with a single stud m7, carried by the rotary key or actuating disk m. Normally the said stud m7 is seated in the slot in the bolt, so that, as in the preferred form of the invention, the said bolt may be sprung and shot without any movement of the actuating mechanism. A

In both forms of the invention the waysf g and s are of a width but slightly greater than that of the studs m3 mf; m7, so that said studs will engage both sides of the said ways, and thus permit the use of the key in both retracting and shooting the bolts.

The socket-plate I) comprises the ordinary face-plate u, having an annular iiange uf of such thickness as to as nearly as possible occupy the space between the downwardly-cxposed face of the abutment c and the plane face of the bolt or bolts and of a width to IOC IIO

leaveafci'rc'ular opening of approximately the Width of the portion I), lthus serving as a seat forl'the said abutment and to engage the bolts both -in a manner Ato insure aclose relation of- -these .parts Whenthelock -is closed.

y'.lfhe'operation of the lioregoing mechanism,

lin so .far as hasnot 'already been described, is asfollovvs- Assuming the lock to `be open, to

; close it it is-fmerelyjnccessary to press it` ro against the socket-plate, which action-.brings the bolts f g into engagement with the fiange u', which engagement by reason of the beveled vface of said bolts forces them Within the bolty chamberb against `thetension of the springs jj', respectively, .to a point Wherey the said bolts .'passl said Jiiange, `whereupon under the said spring tensionthey are automatically shot or .projected from the said chamber beneathv said-flange. The curved shoulder of each abutment .f3 g3, in .conjunctioniwith the opposed spring action, serves to holdthe bolts.

steady longitudinally, said boltslaterally and vvertically. being steadied by the Way, formed l by the stud e and spring-seats 7L and 1l and by f insuressynchronous action-of both bolts. Ther the disk m and the bottom plate d, respee: tively.V .fltwillbe observed that the bolts are the only parts of the lockv mechanism affected by thisfoperation, exceptingthe link c, which curved edge of each bolt insures the complete retraction'-1thereof within thebolt chamber Aandalso a proper clearance ,of the socket-plate flange with a minimum movement of the'bolts.y

The abutment crests upon the said'plate, and

as thespacebetween said abutment and.'said bolt isapproximately equal. to thethickness ofthe ange-there is no looseness of the lock;

when closed.4 'Torelea'se the lock, it is merely necessary to rotate the disk m upon the studV e by means of a special. key adapted to actuate the-tumblersn in the usual [manner torely lease the catch m and to permitsuch rotation. The tumblers and their springs being mounted on an immovableportion ot the casing arenot vaffected by the movement of parts, and their fulcrumfpin and tension-piny areiso disposed l as to `require no special construction-of-.anylof the Working parts. rlhe said disk m is-held f r. inplace bythecatch mf. and the bearing-piece mboth of Whichengage theupper closing-y justed, the link In is substantially inoperative during this action. If there -is a tendency on the part of the ybolts to bind in any Way, positive pressure may be' brought to bear on said bolts by the rotation of the disk 'm in the reinvention. 1

verse direction, the studs mi m3 being adapted v to engage the .oppositeface of the Way ffcg during suchreverse movement. .The springs jj", however, are usually of suiiciient tension to shoot thebolts, and by reasonof the scar-fed corners of said waysand the 'rounded surface of the studs mi mi thedisk m and its .tumblers Will Y normally be automatically'-restoredlto` their original inoperative position.;` l y The operation of the modiiication shovvn'in Figsg and 6 isf-substantially identical .With

th'atof the preferred form, except that thef I single boltqfisY actuated instead of two bolts simultaneously. Y-

` It will be observed thatb-y the construction 'heretofore show-n and described a reliable spring-lock is obtained the partsofwhich are simplegin their construction and so-assembled" as not to be liable to `disarrangement or` unf `due Wear and y,that the arrangementof bolts vis such as. toj `insure a proper resistance' throughout to the various strainsthereupon when they -are shot.4
